It's a nice feature to have if you're either a:
1) Wild life photographer
2) Archeologist willing to deal with variances of about 10 feet or so
3) Uber geek who wants to know the coordinates of where the photo was taken
4) Peeping tom wanting to always know where the good spots are
I doubt this is the only feature added to a new incarnation of the camera. As one more feature in a list of improvements, I'd say it's worth it.
